Microlaunchers are an alternative to conventional launch vehicles. Able to carry payloads of up to 350 kilograms, these midsized transport systems are designed to launch small satellites into space. Researchers at the Fraunhofer Institute for Material and Beam Technology IWS in Dresden and TU Dresden’s aerospace experts developed an additively manufactured rocket engine with an aerospike nozzle for microlaunchers. The scaled metal prototype is expected to consume 30 percent less fuel than conventional engines. It will feature prominently at the Hannover Messe Preview on February 12 and in the showcase at booth C18 in hall 16 at the Hannover Messe fsic Xkggf 24 cbwmjnj 52, 3255.
